While digging around through my 2023 Niro EV's settings, I came across the screen that allows you to select the charging current. But instead of actual numbers (in kW), the options include "maximum," "reduced," and "minimum" (or something to that effect). Obviously "max" and "min" will force the car to request the top speed and slowest speed available from the EVSE. But does anyone know what "reduced" will do? Split the difference? Stick with a middle-of-the-road (pardon the pun) 4.8 kW current or something like that?

While I haven't seen the settings in the '23 EV, from other experience those settings are using only when charging with a 120v EVSE (which I understand Kia doesn't provide with the '23 EV). That's because most 120v EVSEs are capable of 12 amps, and on some homes (especially older ones) that might be too high a current level to sustain. Most only have a max/min setting, which is usually 12/8 amps. Since yours has 3 steps, it's probably 8/10/12 amps. If you're using a 240v EVSE (which is highly likely), that setting does nothing.
Makes sense. Thanks. I sure wish the owner’s manual was as helpful as this forum!
I was troubleshooting my flaky charging and set it to reduced. The car still pulled all 7.5k my charger could deliver once it actually started charging. So it could be a range from 11kw OBC limit down, or it could indeed be only applicable to the L1 charging.
Hmm. I wish we had a definitive answer. Here’s my situation:
I inherited a 30a EVSE but only have a 30a circuit to put it on. While it definitively works, I know it’s supposed to have a 40a circuit, which I can’t do without significant expense. Or I buy a 24a EVSE instead, which seems a bit redundant considering I already have the one I inherited.
So I was hoping there was a way to limit the Niro’s OBC to 24a using the car’s software settings. I’m just not sure it’s set up that way.

I can check next time I attempt to charge. The car reports charging rate and I can also look at my house Sense monitor to see what it pulls at minimal setting. But that's a bit risky in your case as you'd be relying on SW setting to not set some wires on fire...(If the car decides to clear the setting for some random reason as an example)
Thanks for checking. Yeah, my situation isn’t ideal. And I see your point about relying on software.
Maybe next time I win the lottery I can upgrade my main house panel and the sub panel in my garage. One can always dream, right?

No, there's no way to limit the L2 charging level in the car's settings. It has to be done at the EVSE. The car settings are for L1 charging only.
Would you mind sharing a link? I’ve thought about getting an EVSE that can do multiple amp settings, but many are relatively expensive. I’d be curious what you found.
I wondered the same thing on my 2022 EV. I basically had to look at the amp meter on my Lectron when playing with the car’s “EV” screen.
This would be different on your 2023 but on my 2022 EV screen I noticed 3 options:
- Maximum = 32A. Which is fine for my 40A garage outlet.
- Reduced = 28A. Which worked so far when using the nephew’s 30A garage outlet.
- Minimum = 16-18A. Which worked when using my dryer’s 20A outlet.
Since the 2023 EV can draw 11kW, I’m not sure how this is done. This European website implies it takes 3 phase power:
Yet chargpoint implies 240V 50A dual phase breaker (or single phase depending how you look at it).
So I’m going to guess based on the above info:
- Maximum = 11kW or 46A single phase
- Reduced = 7.4kW or 32A
- Minimum = 3.7kW or 16A

So my 2023 EV is getting 7.6 kw using a ChargePoint configured as 40 amps with 50-amp breakers. Should mine get 11kwh then if I select maximum as I have not done that yet.

Thanks for the update.
Have you had issues with passenger seat making noise if no one is sitting there! I think it is the seatbelt making the noise.
May be a bit. I am still chasing occasional refusal to charge on L2...
My '19 Niro would rattle the rear seat belts if the last user left it with a turn/twist of the belt. They have to hang straight so they don't hit the interior while hanging there.
If your Chargepoint is set to 40A, you need to increase it. Can you make it 48A? Then when you set your EV screen to Maximum you should see your 11kW rate (46A). You will then be getting close to your breaker rating (50A). Just monitor the temperature of that breaker and stop charging if it gets too hot.

I thought 48 amps needed to be hard wired? Mine is a plug
Can only charge 80% of breaker rating, so 40A max for a 50A breaker.
